#12425: With -O1 and above causes ghc to use all available memory before being killed by OOM killer -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: high | Milestone: 8.0.2 Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): A guess would be that in 8.0’s library version, `liftM` is implemented in a way that mentions `fmap`, and `liftM` is inlined to expose that. Then all your unconditinally marked inline functions become effectively recursive, but still keep inlining. But didn’t investigate deeper. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12425#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
